LOCK.

Specification of Letters Patent.

Patented June 15, 1909.

Application led March 18, 1908. Serial No. 421,798. i

To all whom it may concern:

Be it known that we, VALTER J. LAMBERT and Erswon'rrr P. Dorrs, both citizens of the United States, and residents, respectively, of North Yakima, in the county of VYakima and State of `Washington, and of Sunnyside, in the county of Yakima and State of iVashington, have invented a new and Improved Lock, of which the following is a full, clear, and exact description.

This invention relates to locks, and more particularly to combination or permutation locks having normally projecting locking bolts, and dials which are adjustable to alter the combinations or permutations of the locks. Y

More specihcally, the invention relates to a lock having a locking bolt which is normally resiliently projected, a member movable in the direction of its length and controlling the locking bolt, a plurality of rotatable disks having openings which, when alined, permit the movement of the member, and a plurality of combination or permutation dials, each controlling one of the disks, the dials being adjustable independently of one another to allow the combination or pernmtation of the lock to be varied.

An object of the invention is to provide a simple, strong and durable combination or permutation lock which is inexpensive to manufacture, which can be easily operated, and which it is practically impossible to unlock without destroying` the lock, unless the proper combination or permutation is known.

A further object of the invention is to provide a lock of the class described, which can be operated to unlock by means only of the proper combination `or permutation, the locking bolt of which can be withdrawn when the lock is properly set, by moving a releasing member in the direction of its length, and in which the combination or permutation dials themselves, are adjustable to permit the varying of the combination or permutation.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specitication, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a front elevation of the lock applied to a desk or other drawer, and showing the dials; Fig. 2 is an enlarged longitudinal section on the line 2 2 of Fig. 1; Fig. 3 is a transverse section on the line 3 3 of Fig. 2; Fig. l is a transverse section on the line wel of Fig. 2; Fig. 5 is a view similar to Fig. 4l, showing one of the parts in a different position; Fig. G is an enlarged front elevation of one of the locking-bolt controlling disks; and Fig. 7 is a rear elevation of one of the dials.

Before proceeding to a more detailed eX- planation of our invention, it should be `clearly understood that while the same is particularly useful in connection with spring drawers for desks and the like, in which it is necessary to have the locking bolt normally projected, it can also be advantageously employed for other purposes to which locks of this character are adapted. 1n most combination or permutation locks it is necessary to take the lock apart in order fto vary the combination by suitably altering Ithe relative positions of certain of the parts. Vith our lock, however, the combination or permutation can be altered by merely adj usting the dials with respect to one another. These dials have the combination or permutation graduations engraved or otherwise indicated thereon, and serve the usual purpose in setting the lock to open it. When the lock has been properly set, the locking bolt can be withdrawn by moving a member in the direction of its length. The member projects from the lock casing and has formed at the end, a push-button. It will be understood that unless the proper combination or permutation is used, the member cannot be moved, and consequently, the locking bolt cannot be released.

Referring more particularly to the drawings, we provide a lock casing 10, which is preferably mounted in a suitable recess of the desk-drawer 11, or other device to which the lock is applied. At the outside of the drawer or other structure, the lock casing has a face-plate 12, preferably flush with the outer surface of the drawer and having a flange 13 secured to the drawer by means of screws or bolts 14 or in any other convenient manner. The casing comprises a lower substantially cylindrical portion 15, and integral therewith, an upper portion 1G of substantially rectangular cross section, and of less width than the diameter of the c ylindrical portion. The casing is formed in halves which are secured together by means of screws or bolts 23. lThe cylindrical portion of the casing, near the lower side, has inwardly disposed parts 2 which present flat faces for the engagement of the bolt heads, as is shown most clearly in Fig. 3.

Arranged longitudinally of the cylindrical portion 15 of the casing is a pintle 17, having one end constructed and, journaled in an opening at the back of the casing. The other end of the pintle 1T extends through a suitable opening of the face plate 12 of the casing. A. sleeve 18 is mounted upon the pintle 1T and is free to move thereon. Near one end, the sleeve 18 has a rigid disk 19, and at the other end has a plurality of sulinstantially radial teeth or projections Q0. rthe end of the sleeve provided with the teeth 20 projects through the opening in the face-plate 12. A second sleeve 21 is movably arranged upon the first sleeve 1S and neai one end has a similar disk 19. The opposite end of the sleeve 2l projects through the opening in the face-plate 1Q and has teeth or projections 20. The sleeve 21 has a collar abutting against the inner side of the face-plate and limiting the projection of the sleeve from the casing. A further disk 19 is rigidly carried. by the pintle 17 and engages at the end of the sleeve 18. The disks 19 are separated a uniform distance, as those carried by the sleeves 1S and L1 are mounted thereon a short distance from the ends of the sleeves, as is shown most clearly in F ig. Q.

The projectingl end of the pintle 17 is provided with peripheral recesses which form teeth 20. A dial Q5 having a substantially central opening having inner peripheral recesses 2G formed to receive the teeth 20, is mounted at the end of the pintle. A second dial 2T having recesses Q6 to receive the teeth 20, is mounted at Vthe end. of the sleeve 18. er further dial. QS, having recesses 2G which receive the teeth 20, is mounted at the end of the sleeve 21. The dials 25, 2T and 2S, increase successively in size and have indicated thereon, combination or permutation graduations 29. A screw 30 lits into a suitably threaded recess at the outer end of the pintle 17 and has the head formed to engage the dial 25 to hold the dials, which overlap, in place. rfhe disks 19 controlled by the dials, have peripheral recesses 31 for a purpose which will appear hereinafter.

An elongated member 32 is movably arranged in openings of the casing and projects through the face-plate of the latter. At the projecting end, the member 82 has a head forming a. push-button. The memtively.

ber is preferably of substantially Vrectangular crosssection and is formed to move through the recesses 31 of the disks 19, when these recesses are alined. The member has transverse edge openings Set which permit the disks to be rotated independently of the member. A collar 35, rigid with the member 32 limits the projection thereof from the lock casing.

fr double bell 'c ank lever 36 is pivoted by means of a suitable pin 37 within the upper portion lt of the casing, and has the lower extremities arranged at each side of the member 32. These lower extremities are bifurcated and straddle studs 38 projecting from the sides of the member, whereby the latter controls the lever.

A locking bolt 39 is arranged within the portion 15 of the casing, at substantially right angles to the member 32, and is movable in the direction of its length. The locking bolt has the upper end projecting through an opening of the casing, and is suitably beveled. The opposite end of the locking bolt. is slidably carried by an inward extension l() of the casing. It has a rigid collar 41, and carries a helical spring l2 which engages the extension 40 and the collar l-1, normally to project the bolt. The

' end of the lever 86 remote from the member Bi', extends at each side of the locking bolt and is pivotally secured to an ear of the latter by means of a pin 43.

lWhen the edge recesses 31 of the disks 19 are not in a-linement, that is, when the combination of the lock is not properly set, the member 32 cannot be moved in the direction of its length. By setting the combination, the recesses 31 are alined and the member 52 can be pushed into the casing by means of its push-button head 33. Then this is done, the lever 3G is swung about its pivot pin 37, and the locking bolt is thereby withdrawn into the lock casing against the tension of the spring 42, and will be held in this inoperative position as long the member 32 is held displaced. then the latter is released, the spring will again project the locking bolt and return the lever and the member 32 to their normal positions. The locking bolt 39 cooperates with a locking plate til having a lug or recess to engage the bolt.

By turning the dials 25, 27 and 2S, the disks 19 can be adjusted to aline their edge recesses 31 to permit the unlocking of the device. Unless the proper combination is known, however, it is extremely difficult to set the lock to permit its opening, Without breaking or otherwise injuring it. In order to vary the combination, the screw 3() is removed and the dials 25, 27 and 28 are successively withdrawn from the ends of the pintle 17 and the sleeves 1S and 21, respec- They can then be replaced in different positions with respect to the pintle and the sleeves, and to each other. The number of the teeth Q0 on the pint-le and on the sleeves, and the number` of the re- Q of the dials will, preferably, correspond to the number of graduations on each of the dials.

Having thns described our invention, we claim as new and desire to secure by Letters Patent:
